Catch dispensing errors before they reach patients.
SAV E-Rx independently analyzes prescription data in real time, helping community pharmacy teams identify high-risk data-entry errors before dispensing. It works alongside—not in place of—your existing pharmacy management software.

The Challenge
Getting Patients the Right Medications is Complex — and the Stakes Are High
Community pharmacies fill over 2 billion electronic prescriptions every year, yet the tools supporting that work have not kept pace. Fragmented data, inefficient systems, manual processes, and rising operational demands create real consequences — for patients, pharmacists, and healthcare businesses alike.

Pharmacist Productivity
Pharmacists and technicians process hundreds of prescriptions daily under intense time pressure. Repetitive manual tasks crowd out the high-value clinical work only a pharmacist can do.

Clinical Care Quality
High-risk patients can go unidentified. Medication treatment is sub-optimal. Medication errors can go undetected. Without better data tools, pharmacists lack the visibility to consistently intervene where it matters most.
Source: Gong et al., BMJ Health and Care Informatics, 2025
Financial & Liability Risk
Malpractice claims average $136,000, audit vulnerabilities go undetected, and missed clinical care opportunities quietly erode margins. Poor data quality has a direct cost to pharmacy operations.

"Prescription errors remain that could be prevented with additional support at the data entry step of e-prescriptions. There is a need to identify potential tools to support data entry and prevent medication errors.

Meet SAV E-Rx
A second set of eyes for every prescription.
SAV E-Rx works alongside—not in place of—your existing pharmacy management software. Its evidence-based safety rules independently compare prescribed and dispensed data to flag potential errors that deserve a pharmacist’s attention.
Independent safety net
Sits outside your pharmacy management software as an added safety layer—it does not replace that software.
Real-time prioritization
Surfaces high-risk discrepancies while pharmacists can still prevent patient harm.
Workflow-aware
Designed to support community pharmacy teams without replacing their established process.
How it works
Three steps to safer dispensing.
Screen every record
SAV E-Rx compares prescribed and dispensed medication data using evidence-based safety logic.
Prioritize meaningful risk
Potentially significant discrepancies are surfaced for focused pharmacist review.
Intervene with context
The pharmacy team reviews the alert, verifies the prescription, and takes the appropriate action.
Published results

Enhancing medication safety with System Approach to Verifying Electronic Prescriptions (SAV E-Rx): pharmacists' review of product selection outcomes between prescribed and dispensed medications
Gong J, Marshall VD, Whitaker M, Rowell B, Dorsch MP, Bagian JP, Lester CA
A retrospective analysis of 1,250,804 records from 14 community pharmacies across 9 US states. SAV E-Rx screened data and identified 662 flagged mismatches; 75 (11.3%) were classified as unintended errors, primarily stemming from human factors. Demonstrates SAV E-Rx as an effective, automated safety net.

Handing off electronic prescription data from prescribers to community pharmacies: A qualitative analysis of pharmacy staff perspectives
Whitaker M, Lester C, Rowell B
Semi-structured interviews with 15 community pharmacy staff revealed that data entry is predominantly a human-reliant process with significant error risk at the product selection stage. Identified the critical need for automated tools to support e-prescription data entry.

Our Platform
Turning Medication Data into Safer, Smarter Care
MeDS builds AI and data pipelines across the full medication use lifecycle. Our platform is designed to deliver impact across four dimensions that matter most to pharmacies, health systems, and the patients they serve.
Medication Safety
Catch errors before they reach patients — automatically and continuously.
Clinical Optimization
Surface high-risk patients and support better therapeutic decisions at scale.
Financial Improvements
Reduce audit risk, liability exposure, and revenue leakage across the dispensing workflow.
Pharmacist Productivity
Automate routine checks so pharmacists can focus on high-value clinical work.
How We Deliver It
Four Critical Pillars of Medication Workflow Intelligence
E-Rx Verification
Electronic Prescribing
AI-powered verification of medication data entry ensures that what's prescribed matches what's dispensed — catching ingredient, strength, and dosage form mismatches before they reach the patient.
- Real-time NDC & RxNorm cross-referencing
- Automated clinically-significant mismatch alerts
- Pharmacist workflow integration
- Schedule II controlled substance safeguards
Dispensing efficiency & Analytics
Medication Dispensing
Data pipelines that monitor dispensing patterns, identify workflow inefficiencies, and surface performance analytics — helping pharmacies operate safely at scale while reducing risk exposure.
- Dispensing pattern analysis
